Valve for a microfluidic system |
| abstract |
The invention relates to a valve for opening and closing a channel ( 3 ) of a microfluidic system, respectively. According to the invention, the valve comprises an actuation medium ( 2 ) that undergoes a volume change with changing temperature; and a heater arrangement ( 5 ) for generating a temperature gradient in the actuation medium ( 2 ) with respect to the actuation medium's ( 2 ) distance relative to the channel ( 3 ); wherein due to an expansion or a contraction of the actuation medium ( 2 ) the channel ( 3 ) is closed or opened, respectively. When the heater arrangement ( 5 ) is activated in such a way that a higher temperature is generated in the actuation medium ( 2 ) which is nearer to the channel ( 3 ) and a lower temperature is generated in the actuation medium ( 2 ) which is further away from the channel ( 3 ) the valve can be closed and vice versa. Accordingly, such a valve for a microfluidic system is provided which can be reliably actuated during a long time of use. |
